实际上，在本机 winforms 中没有托管方式对托盘执行这种形式的动画，但是您可以 P/Invoke shell32.dll 来执行此操作：
这里有一些很好的信息（在评论中不是帖子）：
http://blogs.msdn.com/jfoscoding/archive/2005/10/20/483300.aspx
这是在 C++ 中的：
http://www.codeproject.com/KB/shell/minimizetotray.aspx
您可以使用它来确定要为您的 C# 版本 Pinvoke 的内容。
this.WindowState = FormWindowState.Minimized
这是内置的方法，大多数时候对我来说都很好。唯一有点奇怪的是，如果您在启动时调用它，有时会有些奇怪，这就是为什么大多数人也会设置 ShowInTaskbar = false 并隐藏表单。
http://msdn.microsoft.com/en-us/library/system.windows.forms.form.windowstate.aspx
这将有助于：
public partial class Form1 : Form
{
public static bool Close = false;
Icon[] images;
int offset = 0;
public Form1()
{
InitializeComponent();
notifyIcon1.BalloonTipText = "My application still working...";
notifyIcon1.BalloonTipTitle = "My Sample Application";
notifyIcon1.BalloonTipIcon = ToolTipIcon.Info;
}
private void Form1_Resize(object sender, EventArgs e)
{
if (FormWindowState.Minimized == WindowState)
{
this.Hide();
notifyIcon1.ShowBalloonTip(500);
//WindowState = FormWindowState.Minimized;
}
}
private void notifyIcon1_MouseDoubleClick(object sender, MouseEventArgs e)
{
this.Show();
notifyIcon1.ShowBalloonTip(1000);
WindowState = FormWindowState.Normal;
}
private void maximizeToolStripMenuItem_Click(object sender, EventArgs e)
{
this.Show();
WindowState = FormWindowState.Normal;
}
private void closeToolStripMenuItem_Click(object sender, EventArgs e)
{
Close = true;
this.Close();
}
// Handle Closing of the Form.
protected override void OnClosing(CancelEventArgs e)
{
if (Close)
{
e.Cancel = false;
}
else
{
WindowState = FormWindowState.Minimized;
e.Cancel = true;
}
}
private void Form1_Load(object sender, EventArgs e)
{
// Load the basic set of eight icons.
images = new Icon[5];
images[0] = new Icon("C:\\icon1.ico");
images[1] = new Icon("C:\\icon2.ico");
images[2] = new Icon("C:\\icon3.ico");
images[3] = new Icon("C:\\icon4.ico");
images[4] = new Icon("C:\\icon5.ico");
}
private void timer1_Tick(object sender, EventArgs e)
{
// Change the icon.
// This event handler fires once every second (1000 ms).
if (offset < 5)
{
notifyIcon1.Icon = images[offset];
offset++;
}
else
{
offset = 0;
}
}
}
此代码经过测试并支持许多选项。
更新：看来我发布得太早了。我还使用下面的 hack 作为我的工具。等待正确的解决方案............
您可以为此使用 Windows.Forms.NotifyIcon。http://msdn.microsoft.com/en-us/library/system.windows.forms.notifyicon.aspx
将 NotifyIcon 添加到表单中，设置一些属性，您就完成了。
this.ShowIcon = false;//for the main form
this.ShowInTaskbar = false;//for the main form
this.notifyIcon1.Visible = true;//for notify icon
this.notifyIcon1.Icon = ((System.Drawing.Icon)(resources.GetObject("notifyIcon1.Icon")));//set an icon for notifyicon
private void Form1_Shown(object sender, EventArgs e)
{
this.Hide();
}
和上面类似...
我有一个调整大小事件处理程序，只要窗口调整大小（最大化、最小化等）就会触发...
public form1()
{
Initialize Component();
this.Resize += new EventHanlder(form1_Resize);
}
private void form1_Resize(object sender, EventArgs e)
{
if (this.WindowState == FormWindowState.Minimized && minimizeToTrayToolStripMenuItem.Checked == true)
{
NotificationIcon1.Visible = true;
NotificationIcon1.BalloonTipText = "Tool Tip Text"
NotificationIcon1.ShowBalloonTip(2); //show balloon tip for 2 seconds
NotificationIcon1.Text = "Balloon Text that shows when minimized to tray for 2 seconds";
this.WindowState = FormWindowState.Minimized;
this.ShowInTaskbar = false;
}
}
这允许用户通过菜单栏选择是否要最小化到托盘。他们可以转到 Windows -> 并单击最小化到托盘。如果选中此项，并且窗口正在调整为最小化，那么它将最小化到托盘。对我来说完美无缺。
我已经为你们编写了一个快速解决方案，这可能不是最有效的方法（我不确定），但它绝对有效！
下面的解决方案成功地将您的 Winforms 应用程序最小化到系统托盘，并使用通知图标在系统托盘中创建一个带有上述菜单项的小图标。而不是我们使用内置库来获取窗口（在这种情况下为 GUI），然后使用布尔值的适当方法，然后我们将窗口最小化到托盘。
private void TransformWindow()
{
ContextMenu Menu = new ContextMenu();
Menu.MenuItems.Add(RestoreMenu);
Menu.MenuItems.Add(HideMenu);
Menu.MenuItems.Add(new MenuItem("Exit", new EventHandler(CleanExit)));
notifyIcon = new NotifyIcon()
{
Icon = Properties.Resources.Microsft_Icon,
Text = "Folder Watcher",
Visible = true,
ContextMenu = Menu
};
processHandle = Process.GetCurrentProcess().MainWindowHandle;
ResizeWindow(false);
}

public static MenuItem RestoreMenu = new MenuItem("Restore", new EventHandler(MaximizeClick));
public void CleanExit(object sender, EventArgs e)
{
notifyIcon.Visible = false;
this.Close();
}
在表单的构造函数中：
this.Resize += new EventHandler(MainForm_Minimize);
然后使用此事件处理程序方法：
private void MainForm_Minimize(object sender, EventArgs e)
{
if(this.WindowState == FormWindowState.Minimized)
Hide();
}
如果您在使其正常工作时遇到问题，请检查您是否有
this.Resize += new System.EventHandler(this.Form1_Resize);
